Forum Post: using external memory as RAM

$

I am using Matlab to program, ezDSP F28335 board.

I am trying to flash the ezDSP F28335, with *.ebss section mapped to external memory. When I power up the board after flashing, my program is not working.

But if I put the *.ebss section in RAM, it is working fine. After a search in internet, I come across a method in which they have mentioned, “XINTF_Enable” has to be uncommented in *.gel file, in order to make the F28335 to configure the external memory and make use of it, whenever it resets.

I feel the problem is because of some software initialization, hardware wise it is perfect, I have made changes in the boot switched to boot from flash.

Kindly suggest me a solution
